How do you know you haven't already been struck by lightning? That would explain a lot....

No. He BREAKS things by TOUCHING them, and the dumbass cannot keep his grubby fat little fingers off of anything he buys, and he thinks that taking it apart makes him knowledgeable about what makes it operate.

And THEN, the dopey dumbfuck wants to blame the makers of the products for his abject stupidity, and refuses to believe us when we tell him that it was HE that broke his gear. He is absolutely as clueless as it gets.

This cannot be a story about you, because there is no way in hell that someone as stupid as you are is an electrical engineer.

That is unusual. People that have been very close to a lightening strike usually find that their ears ring for a couple of hours maybe longer and take a while to recover. Our building with a large metal roof took a direct hit that went down the phone lines - turned out later someone had nicked the exterior copper lightning conductor.

All that was left was a charred blackened mess on the wall where the phone trunking had been and into the switchboard. The switchboard girls were very upset, in tears and initially quite deaf. Building lost power too. Damage was mostly confined to the vertical path of the arc. It was a very big bang for everyone in the building but must have been absolutely terrifying in the small reception and switchboard room.

why

Local ground wire for a domestic phone?

I have once had a minor belt off my terrestrial TV roof aerial lead whilst rewiring it to take a satellite dish feed. There was enough static HT on it to light a neon screwdriver - a storm was coming but I didn't know that at the time. Careless not to have checked first.

"Lightening strike"? What is that, a pre-emptive strike with a large bottle of bleach?
